   ITEM 1.  BUSINESS


   CORPORATE PROFILE


      Cognex Corporation ("Cognex" or the "Company," each of which term
   includes, unless the context indicates otherwise, Cognex Corporation and its
   subsidiaries) was incorporated in Massachusetts in 1981. Its principal
   executive offices are located at One Vision Drive, Natick, Massachusetts
   01760 and its telephone number is (508) 650-3000.

      The Company designs, develops, and markets a family of machine vision
   systems that are used to replace human vision in a wide range of
   manufacturing processes. These high-level systems consist of sophisticated
   image analysis software and high-speed, special-purpose computers (vision
   engines) which, when connected to a video camera, interpret and generate
   information about video images. For example, a Cognex machine vision system
   can locate an object, read alphanumeric characters, detect flaws, or measure
   dimensions.

      Machine vision systems are used in a variety of industries including the
   semiconductor, electronics, automotive, consumer products, packaging,
   pharmaceutical, healthcare, metals, and paper industries for applications in
   which human vision is inadequate due to fatigue, visual acuity or speed, or
   in instances where substantial cost savings are obtained through the
   reduction of direct labor and improved product quality. Today, many types of
   manufacturing equipment require machine vision because of the increasing
   demands for speed and accuracy in manufacturing processes, as well as the
   decreasing geometries of items being manufactured.


   WHAT IS MACHINE VISION?


      In a typical machine vision application, a video camera positioned on the
   production line captures an image of the part to be inspected. The machine
   vision computer then uses sophisticated image analysis software to extract
   information from the image and provide an answer to a question. Cognex
   machine vision systems can answer four types of questions:

     GUIDANCE

     Where is it?          Determining the exact physical         Determining the position of a printed circuit board
                           location of an object.                 so that a robot can automatically be guided to insert
                                                                  electrical components.

     IDENTIFICATION

     What is it?           Identifying an object by analyzing     Identifying the serial number on an automotive
                           its shape or by reading a serial       airbag so that it can be tracked and processed
                           number on it.                          correctly through manufacturing.

     INSPECTION

     How good is it?       Inspecting an object for flaws or      Inspecting the quality of printing on pharmaceutical
                           defects.                               labels and packaging.

      Once the machine vision system has processed the image and made any
   necessary analysis, the result is then communicated to other equipment on the
   factory floor, such as an industrial controller, a robotic arm, a deflector
   which removes the part from the line, a positioning table that moves the
   part, or alternatively, to a computer file for analysis or subsequent process
   control. This process is repeated for each part on the line, or continuously
   for process material, as it moves into position in front of the camera.
   Machine vision systems can perform inspections quickly enough to keep pace
   with machines that process thousands of items or material feet per minute,
   thus increasing both quality and productivity.


   THE MACHINE VISION MARKET


      The machine vision market can be segmented into two categories: original
   equipment manufacturers (OEMs) and the factory floor. The factory floor can
   be further subdivided between system integrators and end users. OEMs are
   companies that build standard products sold as capital equipment for the
   factory floor. These customers, most of which are in the semiconductor and
   electronics industries, have the technical expertise to build Cognex's
   programmable, board-level machine vision systems directly into their
   products, which are then sold to end users.

      System integrators are companies that create complete, automated
   inspection solutions for end users on the factory floor in a variety of
   industries. For example, they combine lighting, conveyors, robotics, machine
   vision, and other components to produce custom inspection systems for various
   applications. Because system integrators encounter a broad range of
   automation problems, they purchase a variety of Cognex products, from
   progammable systems to application-specific solutions tailored to solve
   particular manufacturing tasks.

      End users are companies that manufacture products, such as radios, phones,
   and ball-point pens, on the factory floor. While they may purchase capital
   equipment containing machine vision or contract a system integrator to build
   an inspection system, many end users choose to purchase machine vision
   directly to solve specific applications on their production lines. Unlike
   OEMs and system integrators, these customers typically have little or no
   computer programming or machine vision experience.


   BUSINESS STRATEGY


      The Company's goal is to expand its position as a leading worldwide
   supplier of machine vision systems for factory automation. The Company's
   current products are designed for factory automation because the Company
   believes that this market currently offers the greatest opportunity for
   selling high value-added, standard products in high volume. Within the
   factory automation market, the Company has historically focused primarily on
   those customers who must have machine vision because of the increasing
   complexity of their products or manufacturing methods.

      Emphasizing high value-added products and applications is important to the
   Company's strategy, because not every segment of the machine vision market
   offers opportunity for sustained profitability. High value added is realized
   in the Company's products in several ways. The primary value added comes from
   offering unique vision software algorithms which solve challenging problems
   better than competing products. The other major mode of realizing high value
   added is by offering products which are complete solutions to known problems,
   incorporating all of the necessary vision software, applications software,
   hardware, and electro-optics. Both modes of realizing high value added
   require the Company to maintain an industry-leading level of investment in
   research, development and engineering.

      Within the factory automation market, the Company has tailored its product
   and support offerings to match the characteristics of its two major segments:
   OEMs and the factory floor. Historically, the OEM segment has been the source
   of the majority of the Company's sales. However, the Company believes that
   the factory floor segment has the potential in the long term to be many times
   larger than 

                                       2
<PAGE>   5
   the OEM segment. Consequently, the Company has invested heavily in developing
   and acquiring products which meet the needs of the factory floor market, and
   in developing a strong worldwide direct sales and support infrastructure. The
   Company will continue to invest in both segments of the market, defending its
   strong position in the OEM segment while expanding in the factory floor
   segment.

       The Company has historically pursued a global business strategy,
   investing in building a strong direct presence in North America, Japan,
   Europe, and Southeast Asia. Approximately 55% of the Company's revenue comes
   from markets outside of the United States. In all of these regions, the
   Company is acknowledged to be a leading machine vision supplier. The Company
   expects to continue to invest in the expansion of direct sales, support,
   local marketing, and local engineering in all of these regions.

      The factory automation market for machine vision is comprised of many
   market niches defined by differing applications requirements, industry, and
   cost/performance. The Company's business strategy includes selective
   expansion into other industrial machine vision applications. This expansion
   is driven both by the internal development of new products and the
   acquisition of companies and technologies. In July 1995, the Company acquired
   Acumen, Inc. ("Acumen"), a developer of machine vision systems for
   semiconductor wafer identification, and in February 1996, the Company
   acquired Isys Controls, Inc. ("Isys"), a developer of machine vision systems
   for high-speed surface inspection. These acquisitions gave Cognex an
   immediate and strong presence in the growing niche markets for semiconductor
   wafer identification and high-speed surface inspection.


   PRODUCTS


      The Company develops and sells a wide range of standard machine vision
   products - proprietary vision software together with vision hardware (vision
   engines) - which require minimal customization and support by the Company.
   The machine vision systems sold by the Company are defined as either general-
   purpose or application-specific products. General-purpose machine vision
   products enable customers to solve a wide range of problems. Customers select
   the tools necessary to solve their vision problem from the Company's vision
   software library and configure their solution by either writing a C-language
   program or utilizing a graphical user interface (GUI). Application-specific
   machine vision products are "packaged" combinations of software and hardware
   that are designed to solve targeted problems without any customization by the
   Company or its customers. All of the Company's current products are on-line
   systems that run at production speeds and locate images in a two-dimensional
   scene. A typical Cognex machine vision system, including software and
   hardware, ranges from $7,500 to $20,000; however, the Company's Web
   Inspection Systems range from $250,000 to $2,000,000. The Company estimates
   that it had sold an aggregate of approximately 52,000 machine vision systems 
   as of December 31, 1996.

      GENERAL-PURPOSE MACHINE VISION SYSTEMS

      Programmable Vision Engines

      Cognex Programmable Vision Engines (PVEs) are board-level vision systems
   programmable in C-language. PVEs are comprised of software and hardware
   "building blocks" that enable customers to construct solutions tailored to
   their application needs. The Company offers a library of vision software
   tools that locate patterns, inspect for defects, measure geometric
   properties, and identify parts. The hardware is a family of vision computers,
   each of which contains an on-board central processing unit (CPU) and
   co-processor, image capture mechanism, memory, and input/output connector,
   enabling the host computer to off-load all vision tasks to the vision
   processor. Customers first choose the most appropriate software tools from
   the vision software library and then select the hardware platform that
   satisfies their speed and price requirements. To create a vision solution,
   users write a C-language program that connects the software blocks
   appropriate for their vision tasks and then run the application on the
   hardware platform. Customers are given the flexibility to configure their own
   vision solutions to a broad range of complex vision problems without detailed
   support from the Company. Cognex vision hardware is functionally and software
   compatible across product lines,

                                       3
<PAGE>   6
   allowing customers to readily upgrade to higher performance systems or to
   change platforms as application needs change.

      The Company currently offers the Cognex 4000 Series, which plugs directly
   into a VME backplane, and the Cognex 5000 Series, which is for personal
   computers (PCs). PVEs are sold primarily to OEMs located in the United States
   and Japan who integrate the vision engines into manufacturing equipment for
   the semiconductor and electronics industries. PVEs are also sold to system
   integrators located principally in North America, Japan, Europe, and
   Southeast Asia, who integrate the vision engines into manufacturing equipment
   for the factory floor in industries ranging from automotive to
   pharmaceutical.

      During 1996, the Company offered the VisionPro product line to satisfy
   an increasing demand for lower-cost, software-only solutions. The Company has
   added increased functionality to the product and has recently focused its
   selling and marketing efforts toward OEMs and system integrators who require
   lower-cost machine vision systems to run simpler applications.

       "Point and Click" Programmable Systems

      The Checkpoint family of vision systems (the Checkpoint 600 for the PC
   and the Checkpoint 800 which plugs directly into a VME backplane) is designed
   for manufacturing engineers who do not program in C-language and who are
   looking for a rapid application development environment. Checkpoint combines
   the Company's existing vision software and standard vision hardware platforms
   with a unique Microsoft Windows-based GUI. Manufacturing engineers utilize
   pull-down menus and dialog boxes in the GUI to create customized vision
   applications. This "point and click" programming environment enables the
   developer to focus on tasks associated with solving the overall vision
   application, freeing the developer from the detail and complexity of
   programming in C-language. The library of vision tools currently available
   with Checkpoint enables users to solve a wide range of inspection, gauging,
   assembly verification, and defect detection problems.

      The Company introduced Checkpoint in 1994 for the factory floor market.
   Checkpoint is sold primarily to end users and system integrators located in
   North America, Japan, Europe, and Southeast Asia in a wide range of
   general manufacturing industries, such as manufacturers of medical devices,
   batteries, power tools, disposable consumer goods, and electronic components.
   Although the application environment is designed for engineers with little
   programming or machine vision experience, deployment of Checkpoint on the
   factory floor requires the services of trained system integrators to
   mechanically and electrically integrate Checkpoint into manufacturing lines.

      APPLICATION-SPECIFIC MACHINE VISION SYSTEMS

      Application-specific products are "packaged" combinations of software and
   hardware that are designed to solve targeted problems without any
   customization by the Company or its customers. The Company's
   application-specific products are designed to address particular requirements
   of certain vision applications and are sold to OEMs, system integrators, and
   end users worldwide. A list of application-specific products is as follows:

      Web Inspection Systems perform high-speed surface inspection on a variety
   of materials manufactured on continuous sheets or "webs." These systems are
   more hardware intensive than other Cognex products and include lighting,
   custom line-scan cameras, and a multi-board vision processing system along
   with the operator workstation. Each system is individually configured by the
   Company's Isys subsidiary to satisfy the customer's specific requirements.

      Surface Mount Device Placement Guidance Package (SMD/PGP), when coupled
   with a Cognex 4000 or 5000 Series machine vision engine, quickly and
   accurately locates fiducial marks on printed circuit boards for alignment,
   inspects the quality of SMD devices, and then guides placement of those
   devices onto printed circuit boards. For high-performance lead inspection in
   time-critical applications, the SMD/PGP tools have real-time image
   acquisition capability, eliminating the need to stop the motion of the
   placement machine in order to capture an image of a moving part.

      Cognex acuReader/Optical Character Recognition (OCR) reads even the most
   degraded serial numbers from semiconductor wafers with near 100% accuracy.

                                       4
<PAGE>   7
      Cognex acuReader/2D reads Automatic Identification Manufacturers (AIM)
   standard Data Matrix symbologies. The two-dimensional codes are used as
   alternative marks for identifying wafers, Integrated Circuit (IC) packages,
   Liquid Crystal Display (LCD) panels, pharmaceutical packages, and for small
   parts tracking applications.

      Cognex acuReader/Optical Character Verification (OCV) verifies the print
   produced by laser, pad, or offset printing equipment.

      Cognex acuFinder locates parts, regardless of rotation and scale, and
   guides robots in the assembly, sorting, and packaging of appliance,
   automotive, consumer, and electronics products.

      Ball Grid Array (BGA) Inspection Package inspects BGA devices for missing,
   misplaced, or improperly formed solder balls.

      Cognex Fiducial Finder, when coupled with a Cognex 4000 or 5000 Series
   machine vision engine, locates fiducial, or alignment, marks on printed
   circuit boards.

      Cognex Print Quality Inspection (PQI), when coupled with a Cognex 4000 or
   5000 Series machine vision engine, quickly and accurately inspects print
   produced by laser, pad, or offset printing equipment.


   RESEARCH, DEVELOPMENT AND ENGINEERING


      The Company engages in research, development and engineering ("R, D & E")
   to enhance its existing products and to develop new products and
   functionality to meet market opportunities. The Company considers its
   on-going efforts in R, D & E to be a key component of its strategy. Three new
   technologies currently being developed by the Company include: (1) PatMax, a
   new method for high accuracy, rotation and scale invariant pattern
   recognition and defect detection, which is anticipated to be introduced in
   the second half of 1997, (2) a digital 3D sensor, which is anticipated to be
   ready for market in 1998, and (3) the Cognex 8000 Series, the next-generation
   vision engine, which is anticipated to be introduced in the second half of
   1997. The Company has begun to file patents on new technologies it has
   developed for PatMax and the digital 3D sensor. In addition to internal
   research and development efforts, the Company intends to continue its
   strategy of gaining access to new technology through strategic relationships
   and acquisitions where appropriate.

      The R, D & E organization consists of software engineering, hardware
   engineering, and research and development. Software engineering is
   responsible for the development of the Company's core image processing and
   image analysis tools, as well as the maintenance, quality assurance, and
   documentation of software products. Dedicated teams within the software group
   are responsible for the development of the VisionPro and Checkpoint product
   lines, and the SMD/PGP tools, along with the development of application
   products used in wire bonders and other custom applications. Hardware
   engineering is responsible for the development of hardware products,
   primarily vision engines and vision chips. The research and development group
   focuses its energies on enhanced vision technology capabilities. The
   Company's Acumen development center is responsible for the development of
   application-specific products for the semiconductor industry, while the
   development of Web Inspection Systems is performed by the Isys engineering
   organization.

      At December 31, 1996, the Company employed 132 professionals in R, D & E,
   most of whom are software developers. The Company's R, D & E expenses totaled
   $19,434,000, $13,190,000, and $9,933,000 in 1996, 1995, and 1994,
   respectively.


   MANUFACTURING


      With the exception of its Web Inspection Systems, the Company's
   manufacturing organization is located at its Natick, Massachusetts
   headquarters. During 1996, the Company substantially completed its transition
   to a turnkey manufacturing operation whereby the majority of component
   procurement, subassembly, final assembly, and initial testing are performed
   under agreement by a single third-party 

                                       5
<PAGE>   8
   contractor. After the completion of initial testing, the third party
   contractor delivers the products to the Company to perform final testing and
   assembly. The products provided by the third party contractor are
   manufactured using specified components and assembly and test documentation
   created and controlled by the Company. Certain components purchased by the
   third party contractor are presently available from a single source.

      The Company's Web Inspection Systems are manufactured in Alameda,
   California. The manufacturing process consists of systems design,
   configuration management and control, component procurement, subassembly,
   integration and final test, quality control, shipment, and installation.
   Certain products are manufactured by third party contractors using assembly
   and test documentation created and controlled by the Company. Certain
   components purchased by the third party contractors are presently available
   from a single source.


   SALES AND SERVICE


      The Company markets its products through a direct sales force in North
   America, Japan, and Europe, and through a direct sales force and distributors
   in Southeast Asia. The Company's distributors do not have any rights of
   return, and payment for products is due upon delivery. Distributors generally
   have non-exclusive distribution rights and there may be more than one
   distributor per territory.

      The Company's direct sales force operates in North America out of its
   Natick, Massachusetts headquarters, its Regional Technology Centers in
   Mountain View, California, and Naperville, Illinois, and its sales offices
   throughout the United States; in Japan out of its Tokyo and Osaka offices; in
   Europe out of its offices in France, Germany, England, and Italy; and
   in Southeast Asia out of its Singapore and Korea offices.

      At December 31, 1996, the Company's direct sales and service force
   consisted of 91 professionals, including sales and application engineers. The
   majority of the Company's sales and service personnel have engineering or
   science degrees. Sales engineers call directly on targeted accounts and
   coordinate the activity of the application engineers. They focus on potential
   customers that represent possible volume purchases and long-term
   relationships. Opportunities that represent single unit sales or turnkey
   system requirements are identified by the sales engineer and turned over to
   an independent system integrator or OEM that uses the Company's products.

      Sales to international customers represented approximately 55%, 59%, and
   62% of revenue in 1996, 1995, and 1994, respectively. One international
   customer based in Japan, Fuji America Corporation, accounted for
   approximately 11%, 16%, and 20% of revenue in 1996, 1995, and 1994,
   respectively. Segment information, including information about foreign and
   domestic operations, export sales, and significant geographic areas, may
   be found in the Notes to the Consolidated Financial Statements, appearing on
   pages 26 and 27 of the Annual Report to Stockholders for the year ended
   December 31, 1996, which is Exhibit 13 hereto, and is incorporated herein by
   reference. Although international sales may from time to time be subject to
   federal technology export regulations, the Company to date has not suffered
   delays or prohibitions in sales to any of its foreign customers.

      The Company sells its products to customers that have entered or are
   expected to enter into volume discount contracts with the Company. These
   contracts are typically for one year and have associated delivery schedules.

      The Company provides software update services and hardware maintenance on
   a contract basis. Software updates are provided via floppy disks and hardware
   maintenance is provided by repairing or exchanging printed circuit boards.
   Programming application services for projects can be contracted with the
   Company on a time-and-material basis only when doing so enhances the sale of
   the Company's standard products. Product courses are provided by the Company
   at its headquarters in Natick, Massachusetts, at its offices in Japan,
   France, Germany, and England, as well as at the customer site when required.
   These courses provide the user with both lecture and laboratory sessions
   covering the use of Cognex products.

   PATENTS AND LICENSES


      Since the Company relies on the technical expertise, creativity, and
   knowledge of its personnel, it utilizes patent, copyright, and trade secret
   protection to safeguard its competitive position. In addition, the Company
   makes use of non-disclosure agreements with customers, suppliers, employees,
   and consultants. The Company attempts to protect its intellectual property by
   restricting access to its proprietary information by a combination of
   technical and internal security measures. However, there can be no assurance
   that any of the above measures will be adequate to protect the proprietary
   technology of the Company.

      The Company's software products are generally licensed to customers
   pursuant to a license agreement that restricts the use of the products to the
   customer's purposes on a designated Cognex machine vision engine. The Company
   has made portions of the source code available to certain customers under
   very limited circumstances and for restricted uses. If source code is
   released to a customer, the customer is required by contract to maintain its
   confidentiality and, in general, to use the source code solely for internal
   purposes or for maintenance. Effective patent, copyright, and trade secret
   protection may be unavailable in certain foreign countries.

      Several users of the Company's products have received notice of patent
   infringement from Technivision Corporation and Jerome H. Lemelson alleging
   that their use of the Company's products infringes certain patents issued to
   Mr. Lemelson. Certain of these users have notified the Company that, in the
   event it is subsequently determined that their use of the Company's products
   infringes any of Mr. Lemelson's patents, they may seek indemnification from
   the Company for damages or expenses resulting from this matter.

      Two users of the Company's products were engaged in litigation with Mr.
   Lemelson/Technivision involving certain of these patents and the validity of
   these patents was placed in issue. One user entered into a settlement
   agreement with Mr. Lemelson, while the second user had the allegations
   dismissed by the court. Although the Company was not named in this
   litigation, it entered into a joint defense agreement with one party named
   therein, who subsequently entered into a settlement agreement with Mr.
   Lemelson for reasons unknown to the Company. The Company is not a party to
   that settlement and has no indemnification claims, or related obligations,
   with respect to that settlement. Certain products sold by the Company, as
   well as the products of others, were identified in connection with this
   litigation, which claimed an allegedly infringing use.

      In June 1995, a Magistrate Judge filed a recommendation that summary
   judgment be entered in favor of the Company's other user that was engaged in
   the aforementioned litigation with Mr. Lemelson/Technivision. This
   recommendation, which was accepted by the U.S. District Court of Nevada in
   April 1996, disposed of all the actions in favor of the user in this case.
   The Company, however, cannot predict the outcome of any similar litigation
   which may arise in the future, or the effect of such litigation on the
   operating results of the Company. The Company does not believe its products
   infringe any valid and enforceable claims of Mr. Lemelson's patents.


   COMPETITION


      The Company competes with other vendors of machine vision systems, the
   internal engineering efforts of the Company's current or prospective
   customers, and the manufacturers of image processing systems. Any of these
   competitors may have greater financial and other resources than the Company.
   Although, the Company considers itself to be one of the leading machine
   vision companies in the world, reliable estimates of the machine vision
   market and the number of competitors are almost non-existent, primarily
   because of definitional confusion and a tendency toward double-counting of
   sales. The primary competitive factors affecting the choice of a machine
   vision system include product functionality and performance (e.g. speed,
   accuracy, and reliability) under real-world operating conditions,
   flexibility, programmability, and the availability of application support
   from the vendor. More recently, ease-of-use 

                                       7
<PAGE>   10
   has become a competitive factor and product price has become a more
   significant factor with respect to simpler guidance and gauging applications.
   The Company competes with the lower-cost, software-only solutions being
   introduced by various competitors on the basis of superior performance and
   price, rather than on price alone, through its VisionPro product line.


   BACKLOG


      At December 31, 1996, the Company's backlog totaled $26,835,000, compared
   to $27,655,000 at December 31, 1995. Backlog reflects purchase orders for
   products scheduled for shipment within six months. The level of backlog at
   any particular date is not necessarily indicative of the future operating
   performance of the Company. Delivery schedules may be extended and orders may
   be canceled at any time subject to certain cancellation penalties.


   EMPLOYEES


      At December 31, 1996, the Company employed 404 persons, including 148 in
   sales, marketing and support activities; 132 in research, development and
   engineering; 54 in manufacturing and quality assurance; and 70 in management,
   administration and finance. Of the Company's 404 employees, 43 are located in
   Japan. None of the Company's employees are represented by a labor union and
   the Company has experienced no work stoppages. The Company believes that its
   employee relations are good.


   ITEM 2:  PROPERTIES


      In 1994, the Company purchased and renovated a 100,000 square-foot
   building located in Natick, Massachusetts. The Company's corporate
   headquarters, principal administrative, sales and marketing, research,
   development and engineering, manufacturing and quality assurance, and support
   personnel are located in this facility. In addition, the Company leases
   facilities in the United States in California, Illinois, and Oregon, as well
   as in Japan, France, Germany, England, Italy, Singapore, and Korea.

      In 1995, the Company purchased an 83,000 square-foot office building
   adjacent to its corporate headquarters. The building is currently occupied
   with tenants who have lease agreements that expire at various dates through
   the year 2000, at which point, the Company plans to take occupancy of the
   building.

      In 1995, the Company began work on a 50,000 square-foot expansion of its
   corporate headquarters, which was completed during the first quarter of 1997.
   However, since the Company's planned hiring over the next several quarters is
   substantially less than anticipated when construction commenced, occupancy of
   this additional space, along with the related operating costs, will be
   delayed until the additional space is needed, which is anticipated to be late
   1997 or early 1998.

   ITEM 3:  LEGAL PROCEEDINGS


      To the Company's knowledge, there are no pending legal proceedings, other
   than as described in "Business - Patents and Licenses," which are material to
   the Company to which it is a party or to which any of its property is
   subject. From time to time, however, the Company may be subject to various
   claims and lawsuits by customers and competitors arising in the normal course
   of business, including suits charging patent infringement.

      There were no matters submitted during the fourth quarter of the year
   ended December 31, 1996 to a vote of security holders through solicitation of
   proxies or otherwise.

                        REPORT OF INDEPENDENT ACCOUNTANTS

                       ON THE FINANCIAL STATEMENT SCHEDULE



To the Board of Directors and Stockholders of Cognex Corporation:


    Our report on the consolidated financial statements of Cognex Corporation
has been incorporated by reference in this Form 10-K from page 29 of the 1996
Annual Report to Stockholders of Cognex Corporation. In connection with our
audits of such financial statements, we have also audited the related financial
statement schedule for each of the three years in the period ended December 31,
1996 listed in Item 14(a) of this Form 10-K.

    In our opinion, the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material respects, the information required to be
included therein.

and the designations, preferences and relative, participating, optional or other

     of shares of any series of the Series Preferred Stock may be increased or
     decreased (but not below the number of shares thereof then outstanding) by
     the Board of Directors in the manner prescribed by law;

     (2)  The rate and times at which, and the terms and, conditions upon which,

     such persons, firms, corporations or associations (including such holders
     or others) and upon such terms as may be deemed advisable by the Board of
     Directors in the exercise of its sole discretion.

     (2)  The relative powers, preferences and rights of each series of the
     Series Preferred Stock in relation to the powers, preferences and rights of

and affairs of the corporation, for its voluntary dissolution or for limiting,
defining or regulating the powers of the corporation, or of its directors or
stockholders, or of any class of stockholders:

     No Director or officer shall be disqualified by his office from dealing or
contracting as vendor, purchaser or otherwise, whether in his individual

he is interested as stockholder, director, trustee, partner or otherwise, with
the corporation or any corporation, trust, association or firm in which the
corporation shall be a stockholder or otherwise interested or which shall hold
stock or be otherwise interested in the corporation, nor shall any such dealing
or contract be avoided, nor shall any Director or officer so dealing or
contracting be liable to account for any profit or benefit realized through any
such dealing or contract to the corporation or to any stockholder or creditor
thereof solely because of the fiduciary relationship established by reason of
his holding such Directorship or office. Any such interest of a Director shall
not disqualify him from being counted in determining the existence of a quorum
at any meeting nor shall any such interest disqualify him from voting or
consenting as a Director or having his vote or consent counted in connection
with any such dealing or contract.

     No stockholder shall be disqualified from dealing or contracting as vendor,
purchaser or otherwise, either in his individual capacity or through any other
corporation, trust, association or firm in which he is interested as

interested in the corporation, nor shall any such dealing or contract be
avoided, nor shall any stockholder so dealing or contracting be liable to

     Meetings of the stockholders of the corporation may be held at any place
within the United States.

     The corporation may be a partner in any business enterprise it would have
power to conduct by itself.

Articles of organization or the by-laws requires action by the stockholders.

     No director of the Corporation shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
notwithstanding any statutory provision or other law imposing such liability,
except for liability of a director (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of

     Classified Board of Directors

(1)  The Directors of the corporation shall be divided into three classes: Class
I, Class II and Class III. Each class shall consist, as nearly as may be
possible, of one-third of the whole number of the Board of Directors. If the
number of Directors is not evenly divisible by three, the Board of Directors
shall determine the number of Directors to be elected initially into each class.
In the election of Directors at the Special Meeting of Stockholders in Lieu of
the 1989 Annual Meeting, the Class I Directors shall be elected to hold office
for a term to expire at the first annual meeting of the stockholders thereafter;
the Class II Directors shall be elected to hold office for a term to expire at
the second annual meeting of the stockholders thereafter; and the Class III
Directors shall be elected to hold office for a term to expire at the third
annual meeting of the stockholders thereafter, and in the case of each class,
until their respective successors are duly elected and qualified. At each annual
election held after the Special Meeting of Stockholders in Lieu of the 1989
Annual Meeting, the Directors elected to succeed those whose terms expire shall
be identified as being of the same class as the Directors they succeed and shall
be elected to hold office for a term to expire at the third annual meeting of
the stockholders after their election, and until their respective successors are
duly elected and qualified: if the number of Directors changes, any increase or
decrease in Directors shall be apportioned among the classes so as to maintain
all classes as equal in number as possible, and any additional Director elected
to any class shall hold office for a term which shall coincide with the terms of
the other Directors in such class and until his successor is duly elected and
qualified.

(2)  Notwithstanding any other provisions of these Articles of Organization or
the by-laws of the corporation or the fact that a lesser percentage may be
specified by law, these Articles of Organization or the by-laws of the
corporation, the affirmative vote of the holders of at least eighty (80%)
percent of the combined voting power of the outstanding stock of the corporation
entitled to vote generally in the election of directors ("Voting Stock"), voting
together as a single class, shall be required to amend, alter, adopt any
provision inconsistent with or to repeal this provision; provided however that
if any such proposal receives the affirmative vote of each holder of at least
15% of the outstanding Voting Stock who also held at least 15% of the
outstanding Voting Stock of the corporation on May 15, 1989, then such proposal
shall require only the affirmative vote of the holders of at least a majority of
the outstanding Voting Stock of the corporation.

     (A)  In addition to any affirmative vote required by law or these Articles
of Organization, and except as otherwise expressly provided in Paragraph (B) of
this Provision:

(as hereinafter defined) with (a) an Interested Stockholder (as hereinafter
defined) or (b) any other corporation (whether or not itself an Interested
Stockholder) which is, or after such merger or consolidation would be, an

          2.   any sale, lease, exchange, mortgage, pledge, grant of a security
interest, transfer or other disposition (in one transaction or a series of

person (whether or not itself an Interested Stockholder) which is, or after such
sale, lease, exchange, mortgage, pledge, grant of security interest, transfer or
other disposition would be, an Affiliate of an Interested Stockholder, directly
or indirectly, of substantially all of the assets of the corporation (including,
without limitation, any voting securities of a Subsidiary) or any Subsidiary; or

          3.   the issuance or transfer by the corporation or any Subsidiary (in
one transaction or a series of transactions) of any securities of the

any other person (whether or not itself an Interested Stockholder) which is, or
after such issuance or transfer would be, an Affiliate of an Interested
Stockholder in exchange for cash, securities or other property (or a combination
thereof); or

          4.   the adoption of any plan or proposal for the liquidation or
dissolution of the corporation proposed by or on behalf of an Interested
Stockholder or any Affiliate of an Interested Stockholder; or

(whether or not itself an Interested Stockholder) which is, or after such
reclassification, recapitalization, merger or consolidation or other transaction
would be, an Affiliate of an Interested Stockholder;

shall not be consummated unless such consummation shall have been approved by
the affirmative vote of the holders of at least eighty (80%) percent of the
combined voting power of the then outstanding shares of Voting Stock (as
hereinafter defined), voting together as a single class. Such affirmative vote
shall be required notwithstanding the fact that no vote may be required, or that
a lesser percentage may be specified, by law, in these Articles of Organization
or in any agreement with any national securities exchange or otherwise.

     (B)  The provisions of Paragraph (A) of this Provision shall not be
applicable to any particular Business Combination (as hereinafter defined) and
such Business Combination shall require only such affirmative vote as is
required by law and any other provision of these Articles of Organization, if
the Business Combination shall have been approved by a majority of the
Continuing Directors (as hereinafter defined) or all of the following conditions
shall have been met.

          1.   The transaction constituting the Business Combination shall 
provide for a consideration to be received by all holders of Common Stock in

<PAGE>   14



          2.   If the transaction constituting the Business Combination shall
provide for a consideration to be received by holders of any class or series of
outstanding Voting Stock other than Common Stock, the aggregate amount of the
cash and the Fair Market Value as of the date of the consummation of the
Business Combination of consideration other than cash to be received per share
by holders of shares of such class or series of Voting Stock shall be at least
equal to the highest of the following (it being intended that the requirements
of this subparagraph 2 shall be required to be met with respect to every class
or series of outstanding Voting Stock, whether or not an Interested Stockholder
has previously acquired any shares of a particular class of Voting Stock):

               (a)  (if applicable) the highest per share price (including any
brokerage commissions, transfer taxes and soliciting dealers' fees) paid in
order to acquire any shares of such class or series of Voting Stock beneficially
owned by an Interested Stockholder (i) within the two-year period immediately
prior to the Announcement Date, (ii) within the two-year period immediately
prior to the Determination Date, or (iii) in the transaction in which it became
an Interested Stockholder, whichever is highest; or

               (b)  the Fair Market Value per share of such class or series of
Voting Stock on the Announcement Date or the Determination Date, whichever is
higher; or

               (c)  (if applicable) the highest preferential amount per share to
which the holders of shares of such class or series of Voting Stock are entitled
in the event of any voluntary or involuntary liquidation, dissolution or winding
up of the corporation;

          3.   The consideration to be received by holders of a particular class
or series of outstanding Voting Stock (including Common Stock) shall be in cash
or in the same form as was previously paid in order to acquire shares of such
class or series of Voting Stock which are beneficially owned by an Interested
Stockholder and, if an Interested Stockholder beneficially owns shares of any
class or series of Voting Stock which were acquired with varying forms of
consideration, the form of consideration for such class or series of Voting
Stock shall be either cash or the form used to acquire the largest number of
shares of such class or series of voting Stock beneficially owned by it. The
price determination in accordance with subparagraphs 1 and 2 of this Paragraph
(B) shall be subject to appropriate adjustment in the event of any
recapitalization, stock dividend, stock split, combination of shares or similar
event;

<PAGE>   15



          4.   After such Interested Stockholder has become an Interested
Stockholder and prior to the consummation of such Business Combination:

               (a)  except as approved by a majority of the Continuing 
Directors, there shall have been no failure to declare and pay at the regular
date therefor the full amount of any dividends (whether or not cumulative)
payable on any outstanding preferred stock;

               (b)  there shall have been (i) no reduction in the annual rate of
dividends paid on the Common Stock (except as necessary to reflect any
subdivision of the Common Stock) other than as approved by a majority of the
Continuing Directors and (ii) an increase in such annual rate of dividends as
necessary to prevent any such reduction in the event of any reclassification
(including any reverse stock split), recapitalization, reorganization or any
similar transaction which has the effect of reducing the number of outstanding
shares of the Common Stock, unless the failure so to increase such annual rate
is approved by a majority of the Continuing Directors;

               (c)  such Interested Stockholder shall not have become the
beneficial owner of any additional shares of Voting Stock at a price lower than
that paid in the transaction in which it became an Interested Stockholder.

          5.   After such Interested Stockholder has become an Interested
Stockholder, such Interested Stockholder shall not have received the benefit,
directly or indirectly (except proportionately as a stockholder), of any loans,
advances, guarantees, pledges or other financial assistance or any tax credits
or other tax advantages provided the corporation, whether in anticipation of or
in connection with such Business Combination or otherwise; and

          6.   A proxy or information statement describing the proposed 
Business Combination and complying with the requirements of the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder (or
any subsequent provisions replacing such act, rules or regulations) shall be
mailed to the stockholders of the corporation, no later than the earlier of (a)
thirty (30) days prior to any vote on the proposed Business Combination or (b)
if no vote on such Business Combination is required, sixty (60) days prior to
the consummation of such Business Combination (whether or not such proxy or
information statement is required to be mailed pursuant to such Act or
subsequent provisions). Such proxy statement shall contain at the front thereof,
in a prominent place, any recommendations as to the advisability (or
inadvisability) of the Business Combination which the Continuing Directors, or
any of

                                     - C-7 -

them, may have furnished in writing and, if deemed advisable by a majority of
the Continuing Directors, an opinion of a reputable investment banking firm as
to the fairness (or lack of fairness) of the terms of such Business Combination,
from the point of view of the holder of Voting Stock other than an Interested
Stockholder (such investment banking firm to be selected by a majority of the
Continuing Directors, to be furnished with all information it reasonably
requests and to be paid a reasonable fee for its services upon receipt by the
corporation of such opinion)

                                                                       ---------

                               COGNEX CORPORATION
                            PLAN OF RECAPITALIZATION
                                  June 27, 1989

     1.   COMMON STOCK. As of the Effective Date (as defined below), Cognex
Corporation (the "Company") will complete a one-for-two reverse stock split
pursuant to which (A) each holder of two (2) shares of the currently issued and
outstanding Class A Common Stock, with $.001 par value per share ("Old Class A
Stock") of the Company will be entitled to receive, in exchange therefor, one
(1) share of the newly authorized but unissued Class A Common Stock, with $.002
par value per share ("New Class A Stock") of the Company and (B) each holder of
two (2) shares of the currently issued and outstanding Class B Common Stock with
$.001 par value per share ("Old Class B Stock") will be entitled to receive, in
exchange therefor, one (1) share of the newly authorized but unissued Class B
Common Stock of the Company with $.002 par value per share ("New Class B
Stock"). Fractional shares will not be issued by the Company and, in lieu
thereof, holders will receive cash in an amount equal to the fair value of that
fractional share as of the Effective Date as determined by the Board of
Directors of the Company. Stockholders must return for exchange all certificates
representing shares of Old Class A Stock and Old Class B Stock in order to
receive cash or certificates representing New Class A Stock or New Class B
Stock. Accompanying the Notice of the Special Meeting is a Letter of Transmittal
for each holder to complete, date, execute and return to the Company together
with all certificates representing Old Class A Stock and Old Class B Stock. The
Transmittal Letter and the certificates will be held by the Company until the
Plan of Recapitalization is approved. Certificates representing the New Class A
Stock and New Class B Stock need not be issued in the event that the Company
completes the total conversion of all of its capital stock to a single series
and class of Common Stock. In such event, certificates representing such single
class of Common Stock will be issued. If the Plan is not approved, the
certificates and the Transmittal Letter will be returned to the holder.

     2.   PREFERRED STOCK. As a result of the reverse stock split approved in
paragraph 1 above, the conversion rates for the Company's currently authorized
Preferred Stock shall be adjusted (and Article 4 of the Articles of Organization
of the Company shall be amended) as follows: (A) the applicable Conversion Rate
for the Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock, upon the consummation of the reverse stock split, shall be five
(5) such that each share of Series A, B and C Preferred Stock converts into five
(5) shares of New Class A Stock and (B) the applicable Conversion Rate for the
Series D Preferred Stock, upon the consummation of

                                                    

<PAGE>   22



the reverse stock split, shall be one-half (1/2) such that each share of Series
D Preferred Stock shall convert into one-half (1/2) share of New Class A Stock.

     3.   AMENDMENTS TO ARTICLES OF ORGANIZATION. As a result of the reverse 
stock split approved in paragraph 1 above, by adoption of this Plan of
Recapitalization, the Articles of Organization of the Company are amended such
that the total number of shares and the par value, if any, of the Common Stock
that the Company is authorized to issue shall be changed from 10,000,000 shares
of Class A Common Stock with $.001 par value per share and 2,500,000 shares of
Class B Common Stock with $.001 par value per share to 5,000,000 shares of Class
A Common Stock with $.002 par value per share and 1,250,000 shares of Class B
Common Stock with $.002 par value per share. In addition, by adoption of this
Plan of Recapitalization, the Articles of Organization are hereby further
amended to increase the number of shares of Class A Common Stock that the
Corporation is authorized to issue from 5,000,000 shares with $.002 par value
per share to 10,000,000 shares with $.002 par value per share (such new shares
to be known as "Common Stock"). The Company need not file two separate Articles
of Amendment to reflect these amendments and may make one filing with the
Secretary of the Commonwealth of Massachusetts showing the ultimate effect to
the Articles of Organization of this Plan of Recapitalization.

     4.   EFFECTIVE DATE. As used herein, the term "Effective Date" shall mean
June 28, 1989.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
   RESULTS OF OPERATIONS

   SUMMARY

   Despite a challenging business environment marked by a slowdown in the
   semiconductor and electronics industries, revenue for the year ended December
   31, 1996 increased 18% over the prior year. The increase in revenue is due
   primarily to increased volume from factory floor customers. Sales to factory
   floor customers increased 71% over 1995 and grew to 35% of revenue in 1996
   from 24% of revenue in 1995. Although sales to Original Equipment
   Manufacturer (OEM) customers increased 40% during the first half of 1996, OEM
   sales decreased 28% during the second half of 1996, resulting in a 1%
   increase year-on-year. In the first quarter of 1996, the Company acquired
   Isys Controls, Inc. ("Isys"), a developer of machine vision systems for
   high-speed surface inspection. Sales of Isys products, which are included in
   the factory floor business, represented 11% of revenue in 1996.

   The Company's financial position remained strong at December 31, 1996, with
   over $200 million in total assets and over $180 million in stockholders'
   equity. Working capital increased 28% from the prior year and represented 76%
   of total assets. Cash and investments increased 48% from the prior year
   primarily as a result of over $50 million of cash generated from operations.

   The following table sets forth certain consolidated financial data as a
   percentage of revenue for the years ended December 31, 1996, 1995, and 1994:

   RESULTS OF OPERATIONS
   YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995:

   The acquisition of Isys in the first quarter of 1996 was accounted for as a
   pooling of interests. The results of operations of Isys for the full year
   ended December 31, 1996 are included in the Company's results. The results of
   operations of Isys for the years ended December 31, 1995 and 1994 were not
   material to the Company's previously reported results, and therefore, these
   prior years have not been restated.

   Revenue for the year ended December 31, 1996 increased 18% to $122,843,000
   from $104,543,000 for the year ended December 31, 1995. Sales to customers
   based in the United States, which grew to 45% of revenue in 1996 compared to
   41% of revenue in 1995, increased $12,597,000, or 30%, over 1995. Sales to
   customers based in Japan increased $739,000, or 2%, over 1995, and sales to
   customers based in Europe increased $3,715,000, or 30%, over 1995.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
   RESULTS OF OPERATIONS (CONTINUED)

   The increase in worldwide revenue for the year ended December 31, 1996 over
   the prior year is due primarily to increased volume from factory floor
   customers. Sales to factory floor customers increased $17,737,000, or 71%,
   over 1995, and grew to 35% of revenue in 1996 from 24% of revenue in 1995.
   The increased volume from factory floor customers includes sales of Isys
   products totaling $13,183,000, or 11% of revenue, for the year ended December
   31, 1996. During the first half of 1996, sales to OEM customers increased
   $13,505,000, or 40%, over the comparable period in 1995, whereas during the
   second half of 1996, sales to OEM customers decreased $12,942,000, or 28%,
   over the comparable period in 1995, resulting in increased OEM sales of
   $563,000, or 1%, year-on-year. The trend in OEM sales experienced in the
   second half of 1996 over the prior year is expected to continue over the next
   few quarters due to the slowdown in the semiconductor and electronics
   industries, from which the Company either directly or indirectly derives a
   significant amount of its revenue.

   Gross margin for the year ended December 31, 1996 was 68% and included a
   $4,231,000 inventory charge to "Cost of revenue," which reduced the margin by
   approximately four percentage points. The charge reflects costs associated
   with excess inventories resulting from product transition plans over the next
   year, as well as reduced production plans caused by the slowdown in the
   semiconductor and electronics industries.

   Excluding the inventory charge, gross margin for the year ended December 31,
   1996 was 72% compared to 78% for the year ended December 31, 1995. The
   decrease in gross margin excluding the inventory charge is due primarily to a
   shift in product mix to lower margin products including Isys products, price
   discounts to some of the Company's larger customers for attaining certain
   volume thresholds, and underabsorbed manufacturing costs resulting from
   reduced production plans. These influences may continue throughout 1997,
   which would result in gross margins for 1997 that approximate the level
   experienced for the full year 1996, excluding the inventory charge.

   Research, development and engineering expenses for the year ended December
   31, 1996 increased 47% to $19,434,000 from $13,190,000 for the year ended
   December 31, 1995. Expenses as a percentage of revenue were 16% in 1996
   compared to 13% in 1995. The increase in aggregate expenses is due primarily
   to higher personnel-related costs to support the Company's continued
   investment in the research and development of new and existing products.
   These higher costs reflect the hiring of additional personnel at the
   Company's corporate headquarters, and Japanese and Acumen subsidiaries, as
   well as the addition of Isys engineers to the Company's talent pool. The
   increase in expenses as a percentage of revenue is due primarily to the
   investment in research and development outpacing the growth in revenue.

   Selling, general and administrative expenses for the year ended December 31,
   1996 increased 10% to $26,261,000 from $23,973,000 for the year ended
   December 31, 1995. Expenses as a percentage of revenue were 21% in 1996
   compared to 23% in 1995. The increase in aggregate expenses is due primarily
   to higher personnel-related costs, both domestically and internationally, to
   support the Company's worldwide operations and further penetrate the factory
   floor market. These higher costs reflect the hiring of additional personnel
   at the Company's corporate headquarters, and Japanese and European
   subsidiaries, as well as the addition of Isys employees resulting from the
   acquisition. The decrease in expenses as a percentage of revenue is due
   primarily to the Company's efforts to control costs during the second half of
   1996, which included the elimination of substantially all company bonuses.

   Investment income for the year ended December 31, 1996 increased 50% to
   $4,726,000 from $3,147,000 for the year ended December 31, 1995. The increase
   in investment income is due primarily to an increased investment base, as
   well as higher returns on invested balances.

   Other income for the year ended December 31, 1996 totaled $678,000, compared
   to other expense of $182,000 for the year ended December 31, 1995. Other
   income (expense) consists primarily of rental income and related expenses
   from leasing the building adjacent to the Company's corporate headquarters,
   which was purchased in June 1995. The increase in other income is due
   primarily to the collection of rental income for a full year in 1996,
   compared to only a half year in 1995.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
   RESULTS OF OPERATIONS (CONTINUED)

   The Company's effective tax rate was 30.5% for each of the years ended
   December 31, 1996 and 1995, excluding the impact of a $10,189,000 charge for
   acquired in-process technology in the third quarter of 1995, which had no
   associated tax benefit.

   YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994:

   Revenue for the year ended December 31, 1995 increased 67% to $104,543,000
   from $62,484,000 for the year ended December 31, 1994. Contributing to the
   revenue increase, each of the Company's major geographic areas, the United
   States, Japan, and Europe, grew in excess of 55% from the prior year. Revenue
   from international customers amounted to $61,924,000 in 1995, compared to
   $38,451,000 in 1994, an increase of 61%. Revenue from domestic customers
   increased 77% over the prior year.

   The increase in worldwide revenue is due primarily to increased volume
   generated from OEM customers. Sales to OEM customers increased $29,792,000,
   or 60%, from the prior year and over 50 new OEM customers were added
   worldwide in 1995. OEM relationships typically take two to five years to
   reach significant sales and volume levels. In addition, sales to factory
   floor customers increased $12,267,000, or 96%, from the prior year and grew
   to 24% of revenue in 1995 from 20% of revenue in 1994. Over 140 new factory
   floor customers were added worldwide in 1995.

   Gross margin as a percentage of revenue was consistent for the year ended
   December 31, 1995 compared to the year ended December 31, 1994, representing
   78% of revenue in both years.

   Research, development and engineering expenses increased to $13,190,000 for
   the year ended December 31, 1995 from $9,933,000 for the year ended December
   31, 1994. Expenses as a percentage of revenue were 13% in 1995 compared to
   16% in 1994. The increase in aggregate costs is due primarily to higher
   personnel-related costs to support the Company's investment in the research
   and development of new and existing products. In 1995, the number of
   employees engaged in research, development and engineering activities
   increased by 39% over the prior year. The decrease in expenses as a
   percentage of revenue is due to revenue growth outpacing the investment in
   research and development.

   Selling, general and administrative expenses increased to $23,973,000 for the
   year ended December 31, 1995 from $16,847,000 for the year ended December 31,
   1994. Expenses as a percentage of revenue were 23% in 1995 compared to 27% in
   1994. The increase in aggregate costs is due primarily to higher
   personnel-related costs, both domestically and internationally, to support
   the Company's worldwide sales effort, in addition to costs related to
   fluctuations in foreign currency exchange rates. In 1995, the number of
   employees engaged in sales, marketing, and support activities increased by
   36% over the prior year.

   As discussed in the Notes to the Consolidated Financial Statements, on July
   21, 1995, the Company acquired Acumen, Inc. ("Acumen") for approximately
   $14,000,000. Of the purchase price, $10,189,000 was allocated to in-process
   technology which was charged to expense in the third quarter of 1995. This
   charge was not deductible for tax purposes. The Company invested considerable
   additional development efforts related to the in-process technology to add
   functionality, increase hardware performance, and conform and integrate the
   technology to the Company's product standards.

   Investment income increased to $3,147,000 for the year ended December 31,
   1995 from $1,462,000 for the year ended December 31, 1994. The increase in
   investment income is due primarily to an increased investment base.

   Other expense for the year ended December 31, 1995 was $182,000. Other
   expense consists primarily of operating expenses, net of rental income, from
   leasing the building adjacent to the Company's corporate headquarters, which
   was purchased in June 1995. Operating expenses in 1995 included certain
   non-recurring costs related to the initial leasing of the building.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
   RESULTS OF OPERATIONS (CONTINUED)

   The Company's effective tax rate for the year ended December 31, 1995 was
   39%, compared to 31% for the year ended December 31, 1994. The increase in
   the effective tax rate is due primarily to the impact of a $10,189,000 charge
   for acquired in-process technology which had no associated tax benefit.

   LIQUIDITY AND CAPITAL RESOURCES

   The Company's cash requirements during the year ended December 31, 1996 were
   met through cash generated from operations. Cash and investments increased
   $43,360,000 from December 31, 1995 primarily as a result of $51,109,000 of
   cash generated from operations, offset by $10,154,000 of capital
   expenditures. Cash generated from operations consists of net income, adjusted
   primarily for the effects of depreciation and amortization and changes in
   current assets and current liabilities, most notably decreases in accounts
   receivable and inventories.

   As discussed in the Notes to Consolidated Financial Statements, the Company
   has substantially completed its transition to a turnkey manufacturing
   operation. At December 31, 1996, the Company had unconditional obligations to
   purchase $3,812,000 of inventory from a third-party contractor within 60
   days.

   Capital expenditures for the year ended December 31, 1996 totaled $10,154,000
   and consisted primarily of expenditures for computer hardware and software,
   and expenditures related to a 50,000 square-foot expansion of the Company's
   corporate headquarters. Future cash requirements related to the expansion
   approximate $800,000, the majority of which is expected be paid out through
   the first quarter of 1997 with anticipated funding from cash generated from
   operations. However, since the Company's planned hiring over the next several
   quarters is substantially less than anticipated when construction commenced,
   occupancy of this additional space, along with the related operating costs,
   will be delayed until the additional space is needed, which is anticipated to
   be late 1997 or early 1998.

   In 1997, the Company will implement a new business system to replace many of
   its existing systems. Future cash requirements related to the new business
   system approximate $2,250,000, the majority of which is expected to be paid
   out through 1997 with anticipated funding from cash generated from
   operations. The new business system is not expected to be fully implemented
   until late 1997 or early 1998.

   In July 1995, the Company acquired Acumen for approximately $14,000,000. The
   purchase price included $8,452,000 in cash, $755,000 of which, at December
   31, 1996, remained to be paid out through the year 2000.

   The Company believes that the existing cash and investments balance, together
   with cash generated from operations, will be sufficient to meet the Company's
   planned working capital and capital expenditure requirements through 1997,
   including potential business acquisitions.

   FORWARD-LOOKING STATEMENTS

   Certain matters discussed in this annual report are "forward-looking
   statements," which are based on expectations of the Company. Actual results
   could differ materially from the expectations made in the forward-looking
   statements as a result of a number of factors, including (1) capital spending
   trends by manufacturing companies; (2) the cyclicality of the semiconductor
   industry; (3) the Company's continued ability to achieve significant
   international revenue; (4) the loss of, or a significant curtailment of
   purchases by, any one or more principal customers; (5) inability to protect
   the Company's proprietary technology and intellectual property; (6)
   inability to attract or retain skilled employees; (7) technological
   obsolescence of current products and the inability to develop new products;
   (8) inability to respond to competitive technology and pricing pressures; and
   (9) reliance upon certain sole source suppliers to manufacture or deliver
   critical components of the Company's products.

   COGNEX CORPORATION - NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   The accompanying consolidated financial statements reflect the application of
   certain accounting policies described in this and other notes to the
   consolidated financial statements.

   Nature of Operations

   Cognex Corporation (the "Company") designs, develops, and markets machine
   vision systems, or computers that can "see." The Company's products are used
   to automate a wide range of manufacturing processes where vision is required.
   The Company's primary customers, Original Equipment Manufacturers (OEMs) in
   the semiconductor and electronics industries, are principally located in
   Japan and the United States.

   Use of Estimates in the Preparation of Financial Statements

   The preparation of financial statements in conformity with generally accepted
   accounting principles requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the balance
   sheet date and the reported amounts of revenues and expenses during the year.
   Actual results could differ from those estimates.

   Basis of Consolidation

   The consolidated financial statements include the accounts of Cognex
   Corporation and its subsidiaries, all of which are wholly-owned. All
   intercompany accounts and transactions have been eliminated. Certain amounts
   reported in prior years have been reclassified to be consistent with the
   current year's presentation.

   Foreign Currency

   The financial statements of the Company's foreign subsidiaries, where the
   local currency is the functional currency, are translated using exchange
   rates in effect at the end of the year for assets and liabilities and average
   exchange rates during the year for results of operations. The resulting
   foreign currency translation adjustments are reported as a separate component
   of stockholders' equity.

   The Company enters into transactions denominated in foreign currencies and
   includes the exchange rate gain or loss arising from such transactions in
   current operations. The Company recorded exchange rate losses of $1,027,000
   and $573,000 in 1996 and 1995, respectively, and an exchange rate gain of
   $230,000 in 1994.

   Cash and Investments

   Cash and investments include cash equivalents, which the Company considers to
   be all investments purchased with original maturities of three months or
   less. Investments having original maturities in excess of three months are
   stated at amortized cost, which approximates fair value, and are classified
   as available-for-sale. The Company considers all of its investments to be
   available for current operations and maintains its investments in securities
   which are highly liquid and would not result in significant losses if sold
   prior to maturity.

   Inventories

   Inventories are stated at the lower of cost or market. Cost is determined on
   the first-in, first-out basis.

   COGNEX CORPORATION - NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

   Property, Plant and Equipment

   Property, plant and equipment are stated at cost and depreciated using the
   straight-line method over the assets' estimated useful lives. Buildings'
   useful lives are 39 years, building improvements' useful lives are ten years,
   and the useful lives of computer hardware, computer software, and furniture
   and fixtures range from two to five years. Leasehold improvements are
   depreciated over the shorter of the estimated useful lives or the remaining
   terms of the leases. Maintenance and repairs are expensed when incurred;
   additions and improvements are capitalized. Upon retirement or disposition,
   the cost and related accumulated depreciation of the assets disposed of are
   removed from the accounts, with any resulting gain or loss included in
   current operations.

   Intangible Assets

   Intangible assets are stated at cost and amortized using the straight-line
   method over the assets' estimated useful lives, which range from five to
   eight years. The Company evaluates the possible impairment of long-lived
   assets, including intangible assets, whenever events or circumstances
   indicate that the carrying value of the assets may not be recoverable.

   Warranty Obligations

   The Company provides its factory floor products with a one-year warranty from
   the date of shipment and all other products with a 90-day warranty from the
   date of shipment. Estimated warranty obligations are evaluated and recorded
   at the time of sale.

   Revenue Recognition

   Revenue from product sales and software licenses is recognized upon shipment.
   Revenue from construction-type projects, which include research and
   development contracts, is recognized using the percentage-of-completion
   method. Losses on projects, if any, are recognized when identified. Service
   and maintenance revenue is recognized as earned.

   Research and Development

   Research and development costs for internally-developed products are expensed
   when incurred until technological feasibility has been established for the
   product. Thereafter, all software costs are capitalized until the product is
   available for general release to customers. The cost of acquired software is
   capitalized for products determined to have reached technological
   feasibility, otherwise the cost is expensed. Capitalized software costs are
   amortized using the straight-line method over the economic life of the
   product, typically three to five years, or based upon the anticipated
   revenues of the product.

   Income Taxes

   The Company accounts for income taxes in accordance with Statement of
   Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes."
   Under the liability method prescribed by SFAS No. 109, a deferred tax asset
   or liability is determined based on the differences between the financial
   statement and tax basis of assets and liabilities as measured by the enacted
   tax rates which will be in effect when these differences reverse. Tax credits
   are recorded as a reduction in income taxes.

   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

   Net Income per Share

   Primary and fully diluted net income per share are calculated based on the
   weighted average number of common and dilutive common equivalent shares
   outstanding during the year. Dilutive common equivalent shares consist of
   stock options, calculated using the treasury stock method.

   FINANCIAL INSTRUMENTS

   Fair Value

   The Company's financial instruments consist primarily of cash and cash
   equivalents, investments, trade receivables, trade payables, and forward
   exchange contracts. The carrying amounts of cash and cash equivalents,
   investments, trade receivables, and trade payables approximates fair value
   due to the short maturity of these instruments. Based on year-end exchange
   rates and the various maturity dates of the forward exchange contracts, the
   Company estimates the aggregate contract value to be representative of the
   fair values of these instruments.

   Concentrations of Credit Risk

   Financial instruments which potentially subject the Company to concentrations
   of credit risk consist primarily of cash and cash equivalents, investments,
   and trade receivables.

   The Company invests in debt instruments of U.S. and state government
   entities. The Company has established guidelines relative to credit ratings,
   diversification, and maturities that maintain safety and liquidity. The
   Company has not experienced any significant losses on its cash equivalents
   and investments.

   A significant portion of the Company's sales and receivables are from
   customers in the semiconductor and electronics industries. The Company
   performs ongoing credit evaluations of its customers and maintains allowances
   for potential credit losses. The Company has not experienced any significant
   losses related to the collection of its accounts receivable.

   Off-Balance Sheet Risk

   In certain instances, the Company enters into forward exchange contracts to
   hedge specific commitments against foreign currency fluctuations. The forward
   exchange contracts are for periods consistent with its committed exposure and
   require the Company to exchange foreign currencies for U.S. dollars at
   maturity, at rates agreed to at the inception of the contracts. The Company
   had no foreign exchange contracts outstanding at December 31, 1996. The
   Company had $1,079,000 of foreign exchange contracts outstanding, all of
   which were in Japanese yen, at December 31, 1995.

   The Company believes that it is more likely than not that the deferred tax

   of $574,000 will expire in the year 2011.

   LEASES

   The Company conducts some of its operations in leased facilities. These lease
   agreements expire at various dates through the year 2002 and are accounted
   for as operating leases. Annual rent expense totaled $1,324,000 in 1996,
   $996,000 in 1995, and $1,378,000 in 1994. Future minimum rental payments

   LEASES (CONTINUED)

   In June 1995, the Company purchased an 83,000 square-foot office building
   adjacent to its corporate headquarters. The building is currently occupied
   with tenants who have lease agreements that expire at various dates through
   the year 2000. Annual rental income totaled $1,326,000 in 1996 and $536,000
   in 1995. Rental income and related expenses are presented on the Consolidated

   COMMITMENTS

   At December 31, 1996, the Company had substantially completed its transition
   to a turnkey manufacturing operation whereby the majority of component
   procurement, subassembly, final assembly, and initial testing are performed
   under agreement by a single third-party contractor. After the completion of
   initial testing, the third-party contractor delivers the products to the
   Company to perform final testing and assembly. At December 31, 1996, the
   Company had unconditional obligations to purchase $3,812,000 of inventory
   from the third-party contractor within 60 days. These purchase commitments
   relate to expected sales in 1997.

   STOCKHOLDERS' EQUITY

   Common and Preferred Stock

   In December 1994, the Company completed a secondary public offering for the
   sale of 2,859,216 shares of common stock.

   On November 14, 1995, the Company announced a two-for-one stock split,
   effected in the form of a stock dividend, payable December 18, 1995 to
   stockholders of record at the close of business December 1, 1995.
   Accordingly, $39,000 representing the par value of the additional shares
   issued was transferred from additional paid-in capital to common stock. These
   consolidated financial statements and related notes have been retroactively
   adjusted, as appropriate, to reflect this two-for-one stock split.

   In April 1996, an amendment to the Company's Articles of Organization was
   adopted to increase the number of authorized shares of common stock from
   60,000,000 shares to 120,000,000 shares.

   The Company has 400,000 shares of authorized but unissued $.01 par value
   preferred stock.

   Stock-Based Compensation Plans

   The Company has adopted the disclosure requirements of Statement of Financial
   Accounting Standard (SFAS) No. 123, "Accounting for Stock-Based
   Compensation." The Company continues to recognize compensation costs using
   the intrinsic value based method described in Accounting Principles Board
   Opinion No. 25, "Accounting for Stock Issued to Employees." No compensation
   costs were recognized in 1996, 1995, and 1994.

   Stock Option Plans

   At December 31, 1996, the Company had 8,672,000 shares approved by the Board
   of Directors and stockholders for grant under the following stock option
   plans: the 1992 Director plan, 352,000; the 1993 Director plan, 320,000; and
   the 1993 Employee plan, 8,000,000. In April 1996, an amendment was adopted to
   increase the number of shares of common stock reserved for issuance under the
   1993 Employee plan from 5,000,000 shares to 8,000,000 shares.

   In connection with the acquisition of Isys Controls, Inc. in February 1996,
   the Company adopted the 1996 Long-Term Incentive Plan. This plan provided for
   the grant of 321,589 shares of either restricted common stock or options to
   purchase restricted stock. Other than restrictions that limit the sale and
   transfer of the restricted stock within twenty years from the date of grant,
   participants are entitled to all of the rights of a stockholder.

   Options vest over various periods, not exceeding eight years, and expire no
   later than twenty years from the date of grant.

   On July 30, 1996, the Company granted 1,177,830 options at the current fair
   market value with similar terms and conditions to previously issued but
   unexercised grants. In exchange for the new grants, employees agreed to
   forfeit their prior options.

   STOCKHOLDERS' EQUITY (CONTINUED)

   Employee Stock Purchase Plan

   Under the Company's Employee Stock Purchase Plan (ESPP), employees who have
   completed six months of continuous employment with the Company may purchase
   common stock semi-annually at the lower of 85% of the fair market value of
   the stock at the beginning or end of the six-month payment period, through
   accumulation of payroll deductions. Employees are required to hold stock
   purchased under the ESPP for a period of one year from the date of purchase.
   Common stock reserved for future sales totaled 485,970 shares at December 31,
   1996. Shares purchased under the ESPP totaled 27,215 in 1996, 16,133 in 1995,
   and 15,840 in 1994. The weighted-average grant-date fair value of shares
   purchased under the ESPP was $6.82 in 1996 and $3.74 in 1995.

   For the purpose of providing pro forma disclosures, the fair values of shares
   purchased were estimated using the Black-Scholes option-pricing model with
   the following weighted-average assumptions used for purchases in 1996 and
   1995, respectively: a risk-free interest rate of 5.3% and 6.1%, an expected
   life of 6 months, expected volatility of 50%, and no expected dividends.

   EMPLOYEE SAVINGS PLAN

   Under the Company's Employee Savings Plan, a defined contribution plan,
   employees who have attained age 21 may contribute 1% to 15% of their salary
   on a pre-tax basis. Employer contributions are made at the discretion of
   management and vest after five years of continuous employment with the
   Company. Employer contributions approximated $300,000 in 1996, $200,000 in
   1995, and $150,000 in 1994.

   SEGMENT INFORMATION

   During the years ended December 31, 1996, 1995, and 1994, one customer
   accounted for $13,765,000, $17,237,000, and $12,655,000, or 11%, 16%, and
   20%, respectively, of revenue.

   ACQUISITION OF ISYS CONTROLS, INC.

   On February 29, 1996, the Company acquired Isys Controls, Inc. ("Isys"), a
   developer of machine vision systems for high-speed surface inspection. Under
   the terms of the acquisition, accounted for as a pooling of interests, an
   aggregate of 1,078,380 shares of Cognex common stock were exchanged for Isys
   common shares, and 253,547 shares of Cognex common stock were exchanged for
   Isys restricted common shares, with similar restrictions. An additional
   68,042 shares of Cognex common stock were reserved for issuance upon exercise
   of Isys stock options which, as a result of the merger, became options for
   the purchase of Cognex common stock. The exchange ratio was 0.1470 of a share
   of Cognex common stock for each share of Isys common stock.

   The results of operations of Isys for the full year are included in the
   consolidated financial statements of the Company for the year ended December
   31, 1996. For all prior years presented, the financial position and results
   of operations of Isys were not material to the previously reported financial
   position and results of operations of the Company, and therefore, prior years
   have not been restated.

   ACQUISITION OF ACUMEN, INC.

   On July 21, 1995, the Company acquired all of the outstanding shares of
   Acumen, Inc. ("Acumen"), a developer of machine vision systems for
   semiconductor wafer identification. The purchase price of $13,950,000
   included $8,452,000 in cash, 96,140 shares of Cognex common stock with a fair
   value of $4,170,000, and Cognex stock options valued at $1,328,000. At
   December 31, 1996 and 1995, $1,935,000 and $3,125,000, respectively, of the
   purchase price remained to be paid out in cash and stock options through the
   year 2001. The acquisition was accounted for under the purchase method of
   accounting. Accordingly, Acumen's results of operations have been included in
   the Company's consolidated results of operations since the date of
   acquisition.

   COGNEX CORPORATION - NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

   ACQUISITION OF ACUMEN, INC. (CONTINUED)

   The purchase price was allocated among the identifiable assets of Acumen.
   After allocating the purchase price to the net tangible assets and to
   deferred compensation costs, which are amortized over eight years, acquired
   technology was valued using a risk-adjusted cash flow model, under which
   future cash flows were discounted taking into account risks related to
   existing markets, the technology's life expectancy, future target markets and
   potential changes thereto, and the competitive outlook for the technology.
   This analysis resulted in an allocation of $2,369,000 to complete technology,
   to be amortized over five years, and $10,189,000 to in-process technology
   which had not reached technological feasibility and had no alternative future
   use, and accordingly, was expensed immediately. Goodwill associated with the
   purchase is being amortized over five years. At December 31, 1996 and 1995,
   unamortized costs associated with the complete technology amounted to
   $1,659,000 and $2,132,000, respectively.

   The following summarized, pro forma results of operations assume the
   acquisition took place at the beginning of the respective years and exclude
   the $10,189,000 charge for acquired in-process technology (in thousands,
   except per share amounts):

   COGNEX CORPORATION - REPORT OF INDEPENDENT ACCOUNTANTS

   TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF COGNEX CORPORATION:

   We have audited the accompanying consolidated balance sheets of Cognex
   Corporation as of December 31, 1996 and 1995 and the related consolidated
   statements of income, stockholders' equity, and cash flows for each of the
   three years in the period ended December 31, 1996. These financial statements
   are the responsibility of the Company's management. Our responsibility is to
   express an opinion on these financial statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
   standards. Those standards require that we plan and perform the audit to
   obtain reasonable assurance about whether the financial statements are free
   of material misstatement. An audit includes examining, on a test basis,
   evidence supporting the amounts and disclosures in the financial statements.
   An audit also includes assessing the accounting principles used and
   significant estimates made by management, as well as evaluating the overall
   financial statement presentation. We believe that our audits provide a
   reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly, in
   all material respects, the consolidated financial position of Cognex
   Corporation at December 31, 1996 and 1995 and the consolidated results of its
   operations and its cash flows for each of the three years in the period ended
   December 31, 1996, in conformity with generally accepted accounting
   principles.

(1)   1996 results include the full year results of Isys Controls, Inc.
      ("Isys"), a developer of machine vision systems for high-speed surface
      inspection acquired in February 1996. The Isys acquisition was accounted
      for as a pooling of interests; however, because the results of Isys for
      prior years were not material to the Company's previously reported
      results, prior years have not been restated.

(2)   Cost of revenue includes a $4,231,000 inventory charge for costs
      associated with excess inventories resulting from product transition plans
      over the next year, as well as reduced production plans.

(3)   Adjusted for the 2-for-1 stock split effective December 18, 1995.
